In　recent　years,　the　“power　restriction”　measures　were　taken　in　many　localities,　industrial　electricity　consumption　was　interrupted,　mainly　in　the　“two　high”　(high　energy　consumption　and　high　pollutant　emission)　enterprises.　Take　the　“power　restriction”　event　in　2021　as　an　example,　this　event　affected　a　wide　range　of　regions　and　disrupted　people’s　livelihood.　It　not　only　refers　to　the　power　switch　and　rationing　measures　taken　by　individual　regions,　but　also　includes　differentiated　policies　implemented　by　over　20　provinces　to　limit　power　supply　and　industrial　production.　This　paper　investigated　in　detail　and　summarized　the　different　requirements　of　power　restriction　across　the　country,　through　the　comparison　of　annual　growth　rates　of　power　generation　and　industrial　added　value，the　comparison　results　of　energy　intensity,　electricity　production,　power　consumption　and　the　industrial　growth　rate　in　each　province　are　analyzed.　Industrial　enterprises　and　related　industrial　chains　were　most　heavily　affected　by　the　“power　restriction”　event，mainly　in　steel,　cement,　electrolytic　aluminum,　industrial　silicon,　textile　printing　and　dyeing,　chemical　fiber,　chemical　and　other　enterprises　with　high　energy　consumption　and　high　pollutants　emission.　The　measures　to　limit　electricity　will　affect　the　normal　production　of　enterprises　to　a　certain　extent,　leading　to　not　only　the　decrease　of　production　efficiency,　but　also　the　increase　of　energy　consumption　and　pollutant　emission　per　unit　product.　Energy　management　measures　such　as　differentiated　electricity　price　have　limited　effect　on　the　output　of　“two　high”　industrial　products,　and　the　economic　leverage　of　differentiated　electricity　price　is　gradually　being　diluted　by　the　price　rise　of　end　products.　This　paper　analyzed　the　reasons　and　explored　several　key　problems　that　need　special　attention.　then　recommended　certain　countermeasures　for　its　appropriate　application　in　the　future.　©　2024,　Editorial　office　of　Journal　of　Resources　and　Ecology.　All　rights　reserved.
